A nation's civil air ensign is its national flag (or a variation thereof) which represents civil aviation in that nation. Typically, it is flown from buildings connected with the administration of civil aviation and it may also be flown by airlines of the appropriate country.[1] A civil air ensign is the equivalent of the civil ensign which represents merchant shipping. Not all countries have civil air ensigns.
